Which of the following expressions gives the flux Φ through a flat surface of area A due to a constant magnetic field of magnitude B which makes an angle θ with the chosen perpendicular to the surface? A :

Φ = B cos θ / A

B :

Φ = A B sin θ

C :

Φ = A B

D :

Φ = A B cos θ

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
